Modern software systems are complex, distributed, and constantly evolving. Whether you’re deploying microservices in Kubernetes or managing legacy systems in the cloud, one truth holds: you need visibility. That’s where telemetry systems come in. They provide the data and structure needed to observe, understand, and operate IT systems with confidence.

In this post, we’ll explore the fundamentals of telemetry systems, how they work, the types of data they handle, and why they’re indispensable for achieving observability.

In the previous post, we explored how to deploy a FastAPI application on AWS Lambda using an ASGI adapter. This is a great option for early-stage projects: it requires zero infrastructure management, supports rapid iteration, and scales automatically.

But as your application matures, Lambda’s trade-offs can become limiting:

• Cost scaling with consistent traffic
• Compute/memory coupling and lack of vertical scaling
• Package size limits and cold starts

That’s why many teams adopt a container-based workflow that can run on both Lambda (via container images) and ECS Fargate. With a little planning, you can build once and deploy to either platform with minimal friction.

When building or expanding a homelab, setting up a Synology NAS is one of several strong options for managing local storage, backups, and remote access. It’s a flexible platform that offers many features typically found in enterprise storage solutions, but in a form factor and price point that’s accessible to home users.

If you’re considering moving more of your important files, services, or backups off of third-party cloud providers and into a system you control, a NAS can be a great fit. (You can read more about why I personally chose Synology here.

These days, everything lives in the cloud — photos, videos, documents, backups. And for a while, it felt like cloud storage was the perfect solution: easy to access, always backed up, and simple to share with others.

But if you’re like me and deal with a lot of files — especially big ones like videos or high-res photos — you’ve probably hit the same wall I did: cloud storage gets really expensive, really fast.

One of the trade-offs of working in the cloud is the risk of vendor lock-in. While cloud platforms offer powerful tools and scalability, they can also tie you into their ecosystem, making it harder to pivot or migrate down the road.

When it comes to building backend APIs in Python, you have a few great frameworks at your disposal—Django, FastAPI, and Flask—each with its own level of complexity and opinionation. Django is feature-rich and great for full-stack apps, Flask is minimal and flexible, but FastAPI stands out as a modern, async-first framework that makes it incredibly easy to build fast, clean, and production-ready APIs.

Building websites has become easier than ever. Numerous platforms and third-party providers now offer tools to create and host websites within minutes, complete with custom domains, analytics, and sleek graphical interfaces.

For straightforward websites or smaller-scale projects, these platforms can be a convenient choice. However, they often fall short when it comes to flexibility, automation, and cost-effectiveness at scale. Many lack robust CLI (Command Line Interface) support for streamlining tasks, can become expensive as your needs grow, or demand significant management effort and a steep learning curve.
